1/4-28 x 3/8 Knurled Point Alloy Steel Socket Set Screw identifies the exact thread and length for a knurled point socket set screw used in machine hardware.
The serrated knurled cup point bites the mating surface and helps resist vibration-driven back-out in blind holes, softer materials, collars, hubs, and adjustment locations.
Typical review points for 1/4-28 x 3/8 include conveyor hardware, packaging machinery, and compact mechanical controls; it may also fit handles, couplings, stops, and light indexing components where a headless set screw keeps the outside of the component clear while point contact provides the holding action.
The 1/4-28 thread designation identifies a UNF inch thread with 28 threads per inch, and the 3/8 in. length should be checked against tapped depth, contact location, and drive access.
The knurled point can be useful where a plain cup point has a tendency to work loose under repeated motion, but final fit still depends on the assembly. Cold Headers focuses on specialty socket products where item-level details matter to the final order.
